Solution

The code you provided is written in Java and it seems like you want to override the equals method in the Account class and then compare two Account objects. Here is the corrected code:

public class Account {
    private int accountNumber;
    private String holderName;
    private double balance;

    public Account(int accountNumber, String holderName, double balance) {
        this.accountNumber = accountNumber;
        this.holderName = holderName;
        this.balance = balance;
    }

    //Override the equals method in the Object class
    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        Account acc = (Account) o;
        return accountNumber == acc.accountNumber &&
                Double.compare(acc.balance, balance) == 0 &&
                holderName.equals(acc.holderName);
    }
}

public class Main {
    public static void main(String args[]) {
        Account accObj1 = new Account(1001, "Chandru", 50000);
        Account accObj2 = new Account(1001, "Chandru", 50000);

        //Invoke the equals method for the above two objects.
        System.out.println(accObj1.equals(accObj2));
    }
}

In the equals method, we first check if the object we are comparing to is the same object, then if it's null or not of the same class. If these checks pass, we downcast the object to an Account and compare the fields. If all fields are equal, the method returns true, otherwise it returns false.

In the main method, we create two Account objects with the same data and compare them using the equals method. The result is printed to the console.
